Subject: Invoking stat -c FMT with a lone format directive of %s, %f, %h, %s,
X-Git-Tag: CPPI-1_12~1312

Invoking stat -c FMT with a lone format directive of %s, %f, %h, %s,
could cause a buffer overrun error.

(print_it): Allocate 2 more bytes, to accommodate our
conversion of the stat %s format string to the longer printf %llu one.
Patch from Guochun Shi.
